6 x 7990's using ASUS BTC mining motherboard WPA2

I've got a machine with a 7990. You need good airflow in the case, otherwise it will run hot. If you try to stuff 4 in one case good luck. I had two 7970's and a 7990 running in one case with a space between the cards and the 7990 still ends up having issues if I don't slow the clock speeds down on the front GPU.
